NELSON NEWMAN, OF SPRINGFIELD, ILLINOIS.

HOOP-FASTENER.

SPECIFICATION forming part of Letters Patent No. 339,006, dated March 30, 1886.

Application filed March 25,1885. Serial No. 160,111. (No model.) v

To all whom it may concern:

Be it known that I, NELsoN NEWMAN, of Springfield, in the county of Sanga'mon, and in the State of Illinois, have invented certain new and useful Improvements in Hoop-Fasteners; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which Figure 1 is a perspective view of my device from the outer side. Fig. 2 is a like view of the opposite side of the same, and Fig. 3 is a perspective view of a barrel having its hoops secured in place by means of said device.

Letters of like name and kind refer to like parts in each of the figures.

My invention is an improvement upon a similar device for which Letters Patent No. 309,487 were granted to me upon the 16th day of December, 1884; and it consists in the construction of the fastener from cast metal in the form substantially as hereinafter specified.

In the annexed drawings, A represents my fastener, which is formed from a flat piece of metal, having preferably a width of about three-eighths of an inch and a length of about one and one-quarterinch,with one end pointed, and at its opposite end provided with an upward-projecting lug, a.

Upon the lower face of the fastener A are provided several teeth, a, which longitudinally have a rearward rake and transversely are made thin and comparatively deep, so as to give to said teeth in cross-section a very pointed shape. Said teeth are arranged side by side at the rear widest portion of said fastener, while at or near the point where the plate is narrow but one toot-h placed centrally is employed.

The body of the fastener A is, as before stated, made pointed at one end by cutting away its edges at such point. Said point is also thinned, and the upper face is preferably slightly rounded transversely.

The fastener described is formed from cast 5 metal, which leaves the body and teeth solid, by which means the device is rendered very strong, the teeth may be given any desired degree of sharpness, and any desired number of such teeth may be formed, while in case of the sheet-metal fastenings heretofore constructed each tooth was formed by partly cutting away a portion of the body, thereby reducing the strength of the latter, and said teeth were necessarily quite blunt in cross-section and difficult to force into the wood of a barrel.

In use the fastening is driven beneath the hoop B of a barrel from the side nearest one of the chines until its rear lug engages with the edge of said hoop, when, by the engagement of the teeth with the contiguous stave, said fastening will be prevented from moving rearward, and said hoop will be held securely in place.

Having thus fully set forth the nature and merits of my invention, what I claim is 1. As an article of manufacture, a cast-metal hoop-fastener having on its inner face one or more ratchet-shaped teeth with sharp longitudinal edges, substantially as and for the purpose described.

2. As an article of manufacture, the hoopfastener fiat and sharp at one end, att-heother end having an outwardly-projecting lug, and provided on its inner face with longitudinallyextending ratchet-shaped teeth, with their inner faces or edges made sharp, substantially as and for the purpose described.

In testimony that I claim the foregoing I have hereunto set my hand this 18th day of March, 1885.

NELSON NEWMAN.
